(Fig. 9). The outwardly presented openings have plates 45, 46, extending thereacross, the margins of which are connected with the flanges, as by lapping joints 47, the margins being connected with the upright walls by suitably welding the same thereto.

The lowerends of the plates 45, 46, are curved inwardly, as at 48, (Fig. 3) following the curveshelves and flanges are and the outer margins ture of the bends between the lower portions of the upright flanges and the outer portions of the shelves, and preferably part-way close the lower ends of the channels, leaving openings 49, in said lower ends for permitting draining of liquid from the channels.

The inner upright wall of each of the channels is provided with an upright slot 51, in which the roll shafts 52, 53, of the wringer rolls are received. One of the outer walls of the channels is provided with a slot 54 through which the operating end of the shaft of the lower wringer roll extends. This operating end may be suitably formed for connection with a suitable operating device, either manual or power.

A support 57 is located in the lower portion of each of the upright channels, being shown as a block fixed to the inner wall of the upright channel by a screw 58. The lower bearings for the wringer rolls rest on these blocks.

A clothes guard 61 is located at each end of the wringer rolls and has a marginal flange 62 along the front and rear and lower margins of the same, the lower portion of the marginal flange sloping downwardly and inwardly, as shown at 63. The margin of the flange is rounded for instance by a curl 64. Each clothes guard is provided with an upright slot 65. The shafts of the wringer rolls are located in these slots. The respective walls of each of the slots 65 are provided with outwardly extending flanges 66 located between the opposing edges of the slot 51 in the inner wall of the upright post, the slot 51 being enlarged at said flanges for forming shoulders 67 upon which the lower ends of the flanges 66 preferably rest for limiting downward movement of the clothes guard, the flanges locating the clothes guard on the upright post in directions in the plane of the clothes guard. The inner wall 32 of the upright post is provided with slots 71 having enlargements 72 through which the heads 73 of pins 74 fixed to the clothes guard are received, the clothes guard being then lowered for locating the shanks of the pins in the narrower portions of said slots for holding the clothes guard toward the post. A drain board 77 is located between the base and the lower wringer roll. This drain board may be tilted for sloping toward either one of the downwardly and outwardly sloping shelves for draining the water toward the tub. The front and rear edges of the drain board are provided with drooping margins 78, (Fig. 6), and the respective ends of the drain board are provided with upwardly extending flanges 79, the outer ends of which are provided with curved bends 80 (Fig. 1) connecting with the bottom of the drain board. The end flanges of the drain board are pivoted at their middle portions on the screws 58.

A spring 82, shown as a leaf spring, is fixed, as by rivets 83, to the .under face of the base, which has an opening 84, into which a curved portion or hump of the spring extends, this hump coacting with the knob for resiliently holding the drain board in assumed tilted positions, but permitting tilting of the drain board by forceful movement thereof.

The top bar 41 has a top wall 91, depending side walls 92 and depending end walls '93, 94, forming a hollow 95 in the top bar. (Figs. 3, 4, 5, 6 and 8) The top bar connects the upper ends of the upright posts, being received canopywise over said upper ends, and is arranged to be releasably secured to the upright posts for peris fixed to the wringer frame.

menses mitting pressure upon the wringer rolls when the top bar is held in position, and permitting relief of such pressure when the top bar is released.

The connecting means between the top bar and the frame proper of the wringer are exemplified as comprising a knob 96 and a hole 97, the wall of which coacts with the knob at one end of the top bar, the knob being shown on the outer wall of the upright post 23 and the hole in the end wall 94 of the top bar. There is a latch at the other end of the wringer which is exemplified as comprising a latching bar 101, exemplified as a leaf spring, the lower end of which (Figs. 1, 2; 3, 4. and 8) It is shown provided with a curved bend 90 102, conforming to the curvature of the bend 48. It is mounted on the plate 45 in the preferred form of the invention. The points of attachment of the leaf spring are at the lower end thereof, as by welding at 103.

Latching parts are located between the upper end of the latching bar and the end wall 93 of the top bar, shown as a lug 105, or bolt normally received in an opening 106 in the end wall 45, and arranged to be received in an opening 104 in the end wall 93 of the top bar, and c0- acting with the lower wall of said opening 104 for latching the top bar to the main frame, the bolt having a rounded upper end. 107 against which the lower edge 108 of the end wall 93 contacts for moving the bolt outwardly by downward movement of the end wall and locating the opening 106 in the end wall opposite the bolt for latching the top bar to the wringer frame.

An endwise movable rod 111 is slidable in bearings 112, 113, fixed to the top bar. (Figs. 3, 4, 5 and 8). The rod is normally resiliently held inward bya spring 114, coiled about a reduced portion of the rod between the bearing 112 and a shoulder 115 on said rod. The outer end of 115- the rod is arranged to pass through the opening 106 in the end plate 45, and through the hole 104 in the end wall 93, and to move the upper end of the latch bar 101 outwardly for releasing its bolt 105 from its complemental keeper or wall in the opening 104, for permitting release of the top bar.

A sleeve 121 is joumaled in a bearing 122 fixed to the top bar. (Figs. 3, 6, 7 and 8). This bearmg may be made in halves, having a parting 1:5 line 123 between them crosswise of the top bar, the respective halves being provided with flanges 124 fixed to the top wall of the top bar, as by welding. The sleeve is journaled in this hearing and has opposed. shoulders 125, 126, between 133 which the bearing is located.

The lower end of the sleeve has wings 127 projecting therefrom forwardly and rearwardly, and fo cams coacting with the end face 126 of the rod 111 for moving said rod upon rocking movement of the sleeve. These wings are shown provided with corners 129 acting to quickly move the reciprocating rod to full extent for release of the top bar with a rocking movement of the sleeve throughout only a short angle. The sleeve is provided with arms 130, normally projecting therefrom parallel with the top bar, and provided with handles 131 at their ends. Pulling or pushing upon either of said handles crosswise of the top bar rocks the sleeve and quickly releases the'latching means.

A spring 135, shown as a bow spring, has its respective ends resting upon the upper bearings 29 cf the wringer rolls, being received in enlargements of the upper ends of the slots 51.

handle 139 for readily turning to the bearing 29 It has a seat 136 at its middle portion, receiving the lower rounded end threaded connection 138 wall of the sleeve. The screw with the inner threaded is provided with a the same and adthe tension of the spring. This spring the wringer rolls for propis resisted by the lu in exerts pressure upon erly squeezing the clothes and top bar.

The releasing means form easily and quickly acting safety means for releasing pressure between the wringer rolls in case of threatened injury to the operator or to goods.

Means are provided for limiting separating movement of the top bar from the main frame so as to prevent flight'of the top bar away from the frame, or excessive movement thereof, which might result in injury to the operator or others. These means are exemplified as'a supplemental holding means, the coacting holding members of which are normally in spaced relation and are arranged to coact upon release of the latching mechanism.

Thus a latch rod 141 has connection with the top bar. (Figs. 2, 3, 4 and 5). It has a hook 142 forming a slot 143, the hook end of the latching rod being received through a slot 144 in the outer wall of the upright post, being inserted through the space 145 between the bearing 29 for theupper wringer roll and the outer wall of the upright recess in which said bearing is received. When the top bar is released, the hook member is projected upwardly with it, the walls of the slot 143 being received about the upper wall 146 forming the upper end of the slot 144 in the outer wall of the upright post, for limiting the extent of outward movement of the top bar away from the wringer frame. The space 145 is shown as a slot in bearing 29.

The holding means are shown of yoke form, there being a pair of the latching rods at the respective sides of the main latching means, connected by a web 149 pivoted in a bearing 150 in the top bar, and exemplified as formed up out of heavy wire having hooks at the respective sides of the latch bar 101, received through upright slots 144 at the respective sides of said latch bar, The holding rods depends from the top bar and the swinging movement of the top bar upon its emergency release tends to throw the holding rods outwardly for insuring engagement between its hooks and the upper end walls of the slot in which they are located. The relation of the holding rod is such as to normally direct the holding rod outwardly. The latch rods 141 may be swung pendulum wise inwardlyout of the slots 144 for removal of-the ,top bar.

In the modification shown in Figs. 10 to 13 inclusive, the outer walls 34 of the upright channels are formed as continuations of the upright flanges and of the bends 48 between the lower ends of said flanges and the .outer ends of the shelves.

A box-like cross-sectionally substantially U- shaped upright member 151 is formed with an inner wall 152 and sidewalls 153, the lower ends of which are curved to conform to the curvature of the bend between the base and side flanges 'of the wringer frame structure. The outer margins of said box-like element are provided with a flange 154, the lower portion of which is curved to correspond with said curvatures. These flanges extend preferably outwardly and are secured, as by welding, to the upright wall, to the base and to the bend between them, for forming of a screw 137, having prising a base is pivoted at its ends said upright posts. said drain board having upthe channel at each'end of the frame for receiving the bearings of the wringer rolls.

The inner and outer walls of these channels are provided with slots and formations similar to the slots and formations of such walls inthe preferred-i exemplification, and,have-the clothes drain board '77 located-thereto the clothes guards and guards 61 :and the on in similar manner drain board in the preferred structure. The outer walls are also provided with securing and latching means and the holding means as in the preferred structure, the lower curved end of the latching bar being secured to the lower bend in the outer well.

The upright flanges preferably terminate at a point below the tops of the upright posts for permitting the top bar to be received over said upright posts. In the preferred form the upper ends of the end plates 45, 46, are provided with inwardly turned flanges 155 fixed to the side walls of the upright channels as by welding.

(Figs. 5 and 8). In the modification shown in Figs. 10 to 12 inclusive, the upper ends 156 of the flanges 25 are severed from the body portions of the flanges and are bent inwardly as inturned flanges and flxed to the side walls of the upright box-like parts 151, as by suitably welding'the same thereto.

The present invention provides a strong wringer frame structure which is compact and so formed as to permit ready passage therethrough of the clothes without injury to or tearing of the clothes, and provides ready manipulation of the parts, as well as quick release of the pressure between thewringer'rolls, and prevents excess movement of the movable parts in effecting said release, for avoiding damage and injury.
